Abstract

International Standards Organization (ISO) Motion Picture Expert Group (MPEG) technology enables computers, communication, and consumer electronics products to use high-quality digital video and is expected to play a critical role in the emerging multimedia movement. Real-time MPEG performance can be achieved in a single chip with commercial VLSI technology, but requires high-performance buses, memory bandwidths, and arithmetic capabilities. For example, the C-Cube MPEG chip consists of a general purpose processor and dedicated image coprocessors, which implement the ISO MPEG standard for a range of quality and resolution levels. Software can be tailored to specific applications and environments of MPEG. There is special hardware support for discrete cosine transforms, subpel resampling, variable length codes, rounding and clipping. The built-in DRAM controller interfaces directly (without glue chips) to standard DRAMs and utilizes fast page mode. The video bus uses International Radio Consultative Committee 601 format (CrYCbY 4:2:2). Interrupt channels handle the movement of data between DRAM and video bus, and between DRAM and bitstream bus. Multiple chips can be combined for higher resolution applications. A fast algorithms for DCT reduces the number of multiplications.
